Billy Joel & Elton John sing Goodbye Yellow Brick road live

Back in 2000 two great artists performed an amazing duet of 'Goodbye Yellow Brick Road' live at Madison Square Garden.

They've been working together for years including Face to Face in 1994 which made them the longest running and most successful concert tandem in pop music history.

Despite a falling out a few years back they seem to have patched things up now and hopefully some more duets will come.
